Japan is the country that experienced the second miserable reactor accident (Fukushima) after Russia (Chernobyl). In addition, it was attacked by an unprecedented tragedy caused by earthquake, tsunami, and four nuclear reactors meltdown, thereby losing all power supply. In the natural world, nuclear power is a technology that generates the substance itself that enables movement from the planet (the earth) where humans live. Nuclear power is an important energy for human prosperity in the future. Ionizing radiation shows a hormesis effect if a small amount of exposure is given, and gives the human a necessary metabolism. The development of scientific technology of radioactive materials, like fire, is a blessing given by great nature. Meanwhile, as a nation, steady implementation of the reactor decommissioning furnace is necessary as a result of nuclear accidents caused by the lack of technical capability. We think that development of this decommissioning technology is an opportunity for national development and should promote technical testing for development of waste furnace technology as one of the most important geological disposal, that is announced by Prof. Tokunaga, advisery board of NUMO.
